I have had a hysterectomy in 1999. In 2009 I had a bladder sling. I am now seeing what appears to be old or dried blood in my underwear with a strange odor. No blood appears when I wipe after using the bathroom. There is also pain when I have sex with my husband. My lower back has een hurting, as well.
